AUTOMOBILE OR MORTOR-CYCLE HORN.

Application filed may 15, 1915. Serial No. 28,259.

To all whom it may concern:

Be it known that I, RAY H. MANSON, a citizen of the United States, residing at Elyria, in the county ofLorain and State of Ohio, have invented certain new and useful Improvements in Automobile or Motor- Cycle Horns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to automobile or motor cycle horns, and more particularly to such horns in which an electric or other suitable motor is employed to cause the ac,- tuation of the diaphragm, preferably through the rotation of a roughened wheel. As is well known, horns of this type are already in general use, so that the object of my invention is to improve upon this type of horn;

In modern practice automobile horns are employed frequently under the hood of an automobile in association with the power plant of the automobile, and it is highly desirable that the horn should occupy but little space, especially in a longitudinal direction, the idea being to provide a horn which will not interfere with the access to the other'machinery. The advantages ofsuch an arrangement will be appreciated,

' especially in connection with six and eight cylinder engines. Horns of this type have also come to be used upon motor cycles,

where the handle bars and other portions of the frame of the motor cycle are already crowded with machinery and accessories. It is very desirable that the horn employed should be small and that it should .not extend far to the rear of the handle bars.

Another feature of my invention is the provision of an electric motor upon which the field coil can be wound directly m a winding machine. This greatly -expedi-tes. and cheapens the manufacture of the horn,

because in the past, so far as I am aware. it has been necessary to wind the fieldjcoil independently of the pole piece, then mount it on the pole piece.

One of the ob ects of my invention. is to.

provide a condensed horn, and especially a flat horn, and at the same time toxpreserve .the efliciency of the horn, producing such a device which is capable of. making a loud signal.

Another object of my invention is to proating parts are frequently actuated at high speeds, strikinghard and frequent blows,

so that anything about the instrument not t1ghtly secured will be jarred. loose. For 1 these reasons, it is difiicult, if not impossible, to employ with success the adjusting means employed upon other types of horns. In

my invention I- employ adjusting mechanism so located, constructed and arranged that the efiect of such jars and blows will be greatly reduced and inmost instances entirely eliminated.

I also alm to provlde suitable and convenient locking means to hold the adjusting mechanism in position after the horn IS'OIICE- adjusted.

Other objects of my invention and the in- I vention itself will probably be better understood from a description of an embodiment Figure 1 is a side ment of my invention with the rear casing cut away, toshow the interior mechanism of the horn. Fig. 2 is a. section, on the line 22 of Fig. 3. Fig. 3 is a rear elevation of.-

elevation of an embodithehorn with the casing removed."- Fig. 4

is a section taken through the pole piece along the line 44 of Fig. 1.

Referring now to the drawing and to the embodiment of the invention illustrated therein, at 4 is shown a frame piece or supporting member, which is here illustrated as a ring of metal having a large opening 5 in the central portion thereof; The sound producing device, here shown as a sonorous diaphragm 6, is supported from this frame piece. -In the form shown this is connected to the front of'the frame piece by any suit-' able means, such as screws or bolts 7, 7 and 7 A casing front 8 is provided which is used in front of the. diaphragm and which is also connected to the member 4 by the members 7, 7 {and 7; The casing front is provided'with an opening 9 for the egress of sound waves and a resonator 10 may be mounted in this opening to direct and accentuate the sound waves. A bracket 11 may also be used to connect the horn to the vehicle.

In the embodiment shown, the motor is illustrated as an electric motor, which is shown at 12. The field of the motor is shown M313 and consists preferably of ayoke is shown at 19 and consists of a limb casing of soft iron. The field is provided with a plurality of Wings 14, 15 and 16, by which it is Connected to the member 4 by the use of screws or other suitable connecting means. 7 to perform the function of connecting the motor to the memberf4, in addition to connecting the diaphragm and casing front to the member 4. The armature of the motor is shown at 18. The field 20, which is parallel to the armature, and a limb 21, which is at an angle to the armayoke is integral with the limbs and both the limbs, the coupling link and the arm 22 are substantially parallel to the diaphragm, making the device very compact and flat. The coupling link 24 is provided With an opening 26 in which there is formed a bearing for one end 27 of the armature shaft. A removable link 30, preferably of brass is connected across the open end of the yoke l9, and is provided with an opening 31 to form a bearing for the other end of the armature shaft.

The commutator is shown at 32 and the roughened wheel at 33. An anvil 34 is mounted on the diaphragm, which is struck by the roughened wheel when the armature is rotated, causing the actuation of the diaphragm and the production of the'signal.

Brushes 35 are mounted in openings in the limbs 20 and 21. Suitable means, such as screws 40 are provided for connecting the link 30 to the yoke. An opening 41 is provided in the wing 14 and a threaded bushing 42 I is screwed into the opening 41, which is interiorly threaded. One end 43 of the bushing bears against the back side of the member 4 at 60. The other end of the bushing is preferably provided with a head 45. The bolt 7' extends through I the bore in the bushing, and a nut 46 is placed on the end of the said bolt.

When it is desired to adjust the horn, that is, toadjust the wheel 33 with respect to the anvil 34, the nut 46 is'loosened and the bushing is rotated, turning against the bearing 60 and raising or lowering one end of the motor through the wing 14. The fastening means 7 and 7" have sufiicient play and resiliency to permit movement I-may'employ the screws 7 and "is turned over at 51.

enough to properly adjust the horn, and when the horn has been adjusted, the nut 46 is screwed down, locking the bushing in position, so that it cannot rotate. llt will readily be appreciated that this adjustment cannot be disturbed, no matter how hard the action of the roughened wheel upon the anvil and diaphragm, or however the horn is shaken, owing to the rotation of the motor armature, not only because the adjusting mechanism has been locked, but because it is so positioned that little or no efi'ect of suchv agitations will reach the adjusting mechanism.

A rear casing 50 is employed, preferably fitting within the front casing, whose edge The casing is fastened on by some suitable means, such as by screws 52 which may be driven into openings in the yoke.

ductors lead from-these binding posts to the brushes, and from the binding posts to the source of current and the circuit controller which are employed, and which are old and well understood.

I have illustrated this embodiment of my invention and the details thereof for the purpose of describing the same.
